J. Cent. South Univ. (2016) 23: 2205-2213 DOI: 10.1007/s11771-016-3278-7 Soil heavy metal(loid)s and risk assessment in vicinity of a coal mining area from southwest Guizhou, China QIN Fan-xin(秦樊鑫)1..., China, were measured to evaluate the level of contamination, and the potential ecological risks posed by the heavy metals were quantitatively estimated. Results reveal that all heavy metals/metalloid......
Evaluation of ecological risk and primary empirical research on heavy metals in polluted soil over Xiaoqinling gold mining region, Shaanxi, China WU Yao-guo(吴耀国)1, XU You-ning(徐友宁)2..., Pb, Cu, Cr, As and Zn concentrations. The concentrations of heavy metals in soil or crop and hair samples were used to assess their potential ecological risks, or to find the responses to these metals......
